PROMONTORY — Aerospace and defense contractor ATK completed a test of its newly developed Large Class Stage I solid rocket motor on May 23 at a testing facility in Promontory.

ATK officials said the new high-performance motor design implements technologies from a number of Air Force developmental programs.

Created with the intention of developing a motor that can be modified for use on a variety of missions — rather than having to design a new propulsion system for each — the design stands to cut future development costs.
